Normalizing NoSQL Database Models

You can use normalization to define relationships if the source collection has a primary key.

To define relationships using normalization, follow these steps:

  1. On the ribbon, click Actions > Normalization.
    The Normalization dialog box appears.
  2. Select appropriate values in the fields. Refer to the following table for field descriptions.

    Field

    Description

    		Additional Information
    Auto NormalizationSpecifies whether the normalization should be through an auto-mechanismIndicates that the source collection is determined through an auto-mechanism
    Source

    Specifies the source collection for normalization

    		 
    Relationship Type

    Specifies the relationship type for normalization

    Auto: Indicates that a parent array forms one-to-many relationships with other child entities and a parent object forms one-to-one relationships with other child entities

    One to One: Indicates that one-to-one relationships are formed between entities

    One to Many: Indicates that one-to-many relationships are formed between entities

    No Relationship: Indicates that no relationship is formed between entities

    Cascading

    Specifies the factors based on which a collection is normalized into multiple collections

    All: Specifies whether all child levels in the source collection are normalized

    Levels: Specifies the number of levels at which a collection is normalized into separate collections. For example, if you set Level to 1, all fields up to level 1 in the hierarchy will be normalized into separate collections.

    Single Subitem: Specifies whether the different levels in a collection are considered as a single sub-item for normalization. This option applies to collections with multiple levels of sub-items.

    Auto Cleanup: Specifies whether the source collection should be deleted after normalization

    Blank Cleanup: Specifies whether the empty collections should be deleted after normalization. The empty collections are displayed if the collection data type is an object.

  3. Click OK.
    The source collection is split into multiple collections.
